INTERLOCKING DEVICE AND THREE-PHASE INTERLOCKING DEVICE FOR DC TO AC CONVERTER |
摘要 |
The disclosure provides an interlocking device and a three-phase interlocking device for a DC to AC converter (DAC). The interlocking device includes a first interlocking circuit and a second interlocking circuit. The first interlocking circuit couples with a first switch and a second switch, controls whether to conduct the first switch according to the logic levels of a first signal, a second signal and a third signal, and controls whether to conduct the second switch according to the logic levels of the first signal and the second signal. The second interlocking circuit couples with a third switch and a fourth switch, controls whether to conduct the third switch according to the logic levels of the first signal, the third signal and a fourth signal, and controls whether to turn on the fourth switch according to the logic levels of the third signal and the fourth signal. |

1. An interlocking device for a DC to AC converter (DAC), comprising:
a first interlocking circuit, coupled to a first switch and a second switch and configured to receive a first signal, a second signal and a third signal, generate a first locking signal for controlling whether to turn on the first switch according to logic levels of the first signal, the second signal and the third signal, and generate a second locking signal for controlling whether to turn on the second switch according to the logic levels of the first signal and the second signal; and a second interlocking circuit, coupled to a third switch and a fourth switch and configured to receive the first signal, the third signal and a fourth signal, generate a third locking signal for controlling whether to turn on the third switch according to the logic levels of the first signal and the third signal and a logic level of the fourth signal, and generate a fourth locking signal for controlling whether to turn on the fourth switch according to the logic levels of the third signal and the fourth signal. |
